After training on Wednesday, Arena ruled the defender out for this weekend's match.

"He's got a little bit of strain. He's not available this week," Arena told reporters. "The following week, we'll wait and see."

With Dunivant unavailable, the Galaxy have several options as A.J. DeLaGarza returned to full training on Wednesday after missing last week's match due to a contusion. Although DeLaGarza admits that he feels better as he looks ahead for Saturday's match.

"I feel better than I did last week. Obviously with guys going out and me feeling better it is an option," said DeLaGarza. "I played center left back and left back is a different spot, but it's on the same side of the field. It's no where that I haven't played before and I'd feel relatively comfortable with it."
